Release Notes for Cisco CDA Visual Quality Experience Application Release 3.10
Limitations and Restrictions
Deprecated sysctl Message Displayed on Serial Console
On the serial console, the system will occasionally display a message of the form:
process `sysctl' is using deprecated sysctl (syscall)
net.ipv6.neigh.eth4.retrans_time; Use net.ipv6.neigh.eth4.retrans_time_ms instead.
No workaround is needed. This has no known operational impact and is a Red Hat Linux binary message.
After a VQE Downgrade, Web Browser Displays Incorrect Fields for VQE-S
AMT, VCDS AMT, or VCPT
After you have downgraded VQE software and then use the downgraded VQE release, it is possible that
incorrect fields will be displayed for VQE-S AMT, VCDS AMT, or VCPT. In this situation, you are
seeing the fields that were provided by your previous VQE release and that have been cached by the web
browser.
The correct VQE-S AMT or VCPT fields will be displayed after you delete the files in your web browser
cache.

Changing System Time Causes Unicast Retransmission and RCC Disruptions
When the system time is changed on a VQE-S that is actively repairing network errors, all Unicast
Retransmissions will stop indefinitely, and output gaps will be seen on the VQE Clients.
• When the system time is moved forward, the VQE-S receives requests for Unicast Retransmission
and RCC but does not send the repairs/RCCs to the VQE Clients on the set-top boxes.
• When the system time is moved backward, all channels go to an inactive state and no Unicast
Retransmission and RCC operations are performed.
For a VQE-S server that is actively repairing network errors, an explicit system time change (that is, by
using the date command) will always result in the failure of Unicast Retransmission and RCC operations
until corrective action is taken.
